MOTOR.

SECIFICATION forming part of Letters Patent No. 326,117, dated September15, 1885.

Application iilcd Jul) 10, 1885. (N'o model.)

To all whom, it may concern:

Beit known that I, HILoN R. HoRToN, of the city of St. Louis, in theState of Missouri,. have'invented a certain new and useful Motor, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

This is a motor having a box or cylinder hung upon an oscillating armand working other fluid under pressure enters the box or cylinder.

I shall describe the motor or engine as if steam were the mediumused5but compressed air or any other fluid under pressure may be used,or gas may be formed, or gas or gases expanded by explosion, and themotor actu ated by any of these means, my invention applying to thedevice by which huid of any kind, having a pressure greater than theusual prcs'sure of the atmosphere, may be rendered available to givemotion to machinery.

Figure l is a side elevation of the engine or motor, showing thecylinder near its outer position. Fig. 2 is an end elevation of same.Fig. 3 is a detail, partly in vertical longitudinal section, showing thecylinder' in its inner position. Fig. 4 is an enlarged end elevation ofthe valve-box and valve, with the cap of same removed and the valve inposition for exhaust. Fig. 5 is a similar view except that the valve isin the position to admit steam or other Huid into the cylinder. Fig. 6is a vertical longitudinal sectionat 6 6, Fig. 4. Fig. 7 is a verticallongitudinal section at 7 7, Fig. 5. Fig. 8 shows a modification inwhich the cylinder is double-ended and works on two plungers. Fig. 9illustratesa modification.

A is the bed-frame, having an upright or post, B, from which ahanger-rod, C, is suspended in the manner of 'a pendulum, the rodoscillating freely on a pin, D.

To the lower end of the rod C is secured the cylinder E, which is shownround in transverse section, but which may be made of any desiredsectional form. The cylinder is curved in the direction of its length,being of segmental form concentric with the point of oscillation D. (SeeFigs. 1, 3, and 8.)

F is a stuffing-box of substantially ordinary construction, by which thecylinder is made to work with a steam-tight joint upon the plunger G.The plunger is made of substantially the same form as the cylinder, andof such size that the cylinder works over it. The plunger is hollow, andhas through its ends holes H and I for the passage of steam (or otherduid) to and from the cylinder.

Thel plunger and the valve-chest J are firmly secured to the basefralneA by bracket K, or

other suitable means.

The valve-chest has a chamber, L, in which the slide-valve M ts snugly,so as to be substantially balanced. N is the induction-port, and O theexhaust-port, of this chamber. The valvechest has a vertical diaphragm,P, through which are the inductionport Q and the exhaust-port R, theformer, Q, when the valve is in its upper position, being inline Withthe opening S through the valve, and the latter, R, being closed by thevalve. (See Fig. 7.) On the other hand,when the valveis in itslowerposition, as seen in Fig. 6, the port Q is closed, and the exhaust-portin communication with the upper part of the chamber L andtheexhaust-port O. The hole H of the plungereud is in constantcommunication with both holes or ports Q, and R.

T is the valvestem, passing through a stuff ing-box, U, in the top ofthe valve-chest, and connected by a pin, V, to one end of the workingbar or lever W, which bar oscillates on a pin, X, projecting from theupright B.

Y is a bar, having at the ends studs y y', which, as the rod Goscillates, are brought in contact with the underside of the workingbarW, and cause the oscillation of the bar W and the vertical movements ofthe slidevalve.

w w are projections against which the studs impinge as the cylinder isjust commencing and is just reaching the end of its forward stroke. Thebar Y is attached to the pitman Z, by which the rod C is connected tothe crank a of the shaft b of balance-wheel c, and thus the bar Y has acompound motion, the oscillation of the pitman causing its-ends to riseand fall as the crank revolves.

Suppose the parts to be in the position shown in Fig. l, in which theexhaust is taking place and the cylinder has commenced its retrogrademovement, beingimpclled by the momentum of the balance-wheel, when thecylinder has reached its inner position, as seen in Fig. 3, and incommencing its forward movement the stud Y comes in contactwith theprojection w and reverses the valve, then the eXhaustis closed andtheinduction opened, and the cylinder is forcibly driven forward.

In the modification shown in Fig. 9, the cylinder is fixed and theplunger secured to the frame B.

In Fig. 8 is shown a modification in which the cylinder is double-endedand works on i two plungers, the movement being thus made positive inboth directions.

rIhe valves may be worked in the manner described.

I claiml. A cylinder supported on an oscillatory rod or frame, andworking over affixed plunger, substantially as set forth.

2. The combination of an oscillating hang` er-rod, a cylinder supportedon the same and curved concentrically'with the axis of oscillation, anda fixed plunger on which the cylindcr works, and which has a passagethrough it for the entrance and exit of fluid, for the purpose setfort-h.

3. The combination of Xed plunger havingr a passage extending throughit, an oscillating cylinder working over it, and a slidevalveconstructed to operate, substantially as described, and actuated byconnection with the oscillating parts.

4. The combination of an oscillatinghanger-rod, a cylinder attached tosaid rod and working over afixed plunger having a passage through it,aslide-valve governing the current of fluid through said passage, andhaving a working bar or lever connected to the valvestem, and actuatedby bar or frame attached to a pitman which connects the hanger-rod tothe crank of a balance-wheel.

5. The combination of the oscillatinghangerrod C, the pitman Z, with barY attached to it, and the working bar or lever W7 having connection withthe Valve-stern T, substantially as and for the purpose set forth.
